Linseed Oilcake & Other Solid Flaxseed Extraction Residues imports of $165K in May 2026 ran 55% below the year-to-date monthly average of $372K.
Last updated: May 2026 dataLinseed cake — the compressed or solvent-extracted residue from flaxseed oil production — is a moderately high-protein feed ingredient notable for its elevated omega-3 fatty acid content relative to other oilseed meals, making it a specialty input for dairy and equine rations. Classified under a single tariff line (2306200000), the product is also traded as flaxseed meal, and its mucilage content can complicate pelleting in compound feed manufacturing. Canada is the dominant US import source, consistent with its status as one of the world's largest flaxseed producers and processors.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Yes — linseed and flaxseed refer to the same crop (Linum usitatissimum), and both linseed cake and flaxseed meal derived from oil extraction classify under 2306200000. The trade name used on commercial documents does not affect classification, but the invoice should clearly identify the product as an oilseed extraction residue rather than a whole or ground seed to avoid misclassification into Chapter 12.
Processed linseed cake is generally not subject to the same APHIS weed-seed restrictions as raw flaxseed, because the oil-extraction process destroys seed viability. However, importers should confirm current APHIS admissibility requirements for the specific product form, as processing conditions (temperature, pressure) may be relevant to demonstrating non-viability. USMCA origin documentation should accompany Canadian-origin shipments.
